General safety summary

General safet

y summary

Review the fo

llowing safety precautions to avoid injury and prevent damage to

this product or any products connected to it.

To avoid potential hazards, use this product only as speciﬁed.

Only qualiﬁed personnel should perform service procedures.

To avoid ﬁre or personal

injury

Use proper power cord. Use only the power cord speciﬁed for this product and

certiﬁed for the country of use.

Connect and disconnect properly. Do not connect or disconnect probes or test

leads while they are connected to a voltage source.

Connect and disconnect properly. De-energize the circuit under test before

connecting or disconnecting the current probe.

Ground the product. This product is grounded through the grounding conductor

of the power cord. To avoid electric shock, the grounding conductor must be

connected to earth ground. Before making connections to the input or output

terminals of the product, ensure that the product is properly grounded.

Observe all terminal ratings. To avoid ﬁre or shock hazard, observe all ratings

and markings on the product. Consult the product manual for further ratings

information b efore making connections to the product.

Connect the probe reference lead to earth ground only.

Do not apply a potential to any terminal, including the common terminal, that

exceeds the maximum rating of that terminal.

Power disconnect. The power cord disconnects the product from the power s ource.

Do not block the power cord; it must remain accessible to the user at all times.

Do not operate without covers. Do not operate this product with covers or panels

removed.

Do not operate with suspected failures. If you suspect that there is damage to this

product, have it inspected by qualiﬁed service personnel.

Avoid exposed circuitry. Do not touch exposed connections and components when

power is present.

Do not operate in wet/damp conditions.

Do not operate in an explosive a tmosphere.

Keep product surfaces clean and dry.

Provide proper ventilation. Refer to the manual's installation instructions for details

on installing the product so it has proper ventilation.

iv MDO4000 Series Speciﬁcations and Performance Veriﬁcation

Speciﬁcations

This chapter contains speciﬁcations for the MDO4000 Series oscilloscopes. All

speciﬁcations are guaranteed unless noted as "typical." Typical speciﬁcations are

provided for

your convenience but are not guaranteed. Speciﬁcations that are

marked with the

symbol are checked in Performance Veriﬁcation.

All speciﬁc

ations apply to all MDO4000 models unless noted otherwise. To meet

speciﬁcations, two conditions must ﬁrst be met:

The oscill

oscope must have been operating continuously for twenty minutes

within the speciﬁed operating temperature range. (See Table 12 on page 23.)

You mu st p

erform the Signal Path Compensation (SPC) operation described

instep2oftheSelf Test before evaluating speciﬁcations. (Se e page 62, Self

Test.) If the operating temperature changes by more than 10 °C (18 °F), you

must perform the SPC operation again.

regardless of the overvoltage protection circuitry because of the ﬁnite time

required to detect and respond.
